Double lift open shed Jacquard loom

Abstract

A double-lift open-shed Jacquard loom comprises hooks controlled by control needles, the leg of each hook having three noses thereon. The loom also has two sets of blades which are movable towards and away from each other by lift means, a stationary set of blades, and at least one hook rake. Bracing means are provided to act on the legs of the ones of said hooks which are disposed on the arresting blades in the open-shed position, to urge said hooks towards the respective lifting blade.

What is claimed is: 
     
       1. In a double-lift open-shed Jacquard loom having a vertically-movable hook, said hook having a leg portion provided with first, second and third noses thereon, having a first blade arranged to selectively engage said first nose, having a second blade arranged to selectively engage said second nose, and having a third blade arranged to selectively engage said third nose, having lifting means for moving said first and second blades upwardly and downwardly in opposite directions towards and away from one another, having a member, and having a control needle for selectively determining which of said blades will engage the associated nose, the improvement which comprises: bracing means acting between said member and said hook only when said third blade engages said third nose for biasing said leg portion laterally such that said first and second noses will be held in operative positions at which they may be selectively engaged by the associated blades.   
     
     
       2. The improvement as set forth in claim 1 wherein said member is a hook rake, and said bracing means includes projections mounted on said leg portion so as to engage said hook rake. 
     
     
       3. The improvement as set forth in claim 1 wherein said bracing means includes a length of wire, having a portion bent to engage said member, mounted on said leg portion. 
     
     
       4. The improvement as set forth in claim 1 wherein said bracing means is a stationary member arranged to engage the upper end of said hook when said third blade engages said third nose.
